.The invention relates Ytolimprovements in incubators of the general type disclosed iny e my U. S. Patent No.- 1,690,169 of December 2, 1927. In -this incubator, 'aplurality of 5 trays are rotatably mounted for turning the eggs, a dial platey is employedfcofoperablei with pointers to allow uniform turning of the trays, and toothed', locking wheels are emv ployed on the shafts'ofthe trays co-operable 10 with keys in locking the trays at any posi,A

tions to which theyfmay bev turned, the'dial plate, locking wheels and keys being removable .when the timearrives for the eggs to hatch. It is the object lof the present inven-v tion to provide effective means for locking all of the trays against possible .tilting vfrom the time the dial plate, locking wheels and keys are removed,` until they hatching Yperiod is over. ff f' f resides in the novel Subj ect matter hereinafter describedjand'claimed, description being accomplished` by reference to the"4 .accompanyingdrawings. f 'y Fig. 1 isa perspective Viewof an incubator constructed in accordance with my invention Vand illustrating-the locking barfor the trays in its normalposition at which itis supported .i l Y wall 14- of theV ldrawerlikejfsimucture,said
